A leader who never says “I don’t know” is teaching everyone else to fake it.

Everything you model becomes normal, including the pretending. If uncertainty never shows in you, people conclude that being unsure is something to hide here, and they cover for it in ways you will not discover until something breaks. Admitting a gap once gives everybody permission to be honest about theirs. The group gets more accurate rather than less confident.

Say the words out loud next time they are true, then say how you will find out. Do it in front of the group rather than privately. Watch who relaxes afterwards and starts asking real questions.
